CeramicSpeed Ceramic MTB Bottom Bracket - BB30 to 24mm (Shimano) Info
The CeramicSpeed Ceramic MTB Bottom Bracket BB30 to 24mm (Shimano) solves one of the more frustrating compatibility problems in mountain biking — running a 24mm-spindle crankset in a BB30 shell — without compromising on bearing quality. Pressed into aluminum cups, CeramicSpeed's Grade 3 Silicon Nitride ceramic balls are seated in hardened steel races and assembled in dust-free clean rooms in Denmark, resulting in a bottom bracket designed to outlast standard bearings by three to five times.
The ceramic balls themselves are the reason riders seek out CeramicSpeed. Compared to standard steel balls, they're 400% smoother, 128% harder, and 58% lighter — and they outperform standard ceramic balls too, measuring over 100% smoother and 15% harder. Less friction under load means more of your power reaches the trail, and reduced wear means fewer service intervals. Compatible with Shimano 24mm-spindle cranks, this unit fits 73mm-wide BB30 shells with a 42mm inner diameter.
